Abstract [en]

This report describes the development and implementation of a system for transmitting digital information at high speeds from a miniaturized submersible developed by the Ångström Space Technology Centre at Uppsala University. For instance, the vehicle shall transmit image data – even stream live video - through an optical fibre to a monitor in a ground station. Hence, the system shall be used both to convert the image data to make it transmittable, and to recreate it at the receiver.

The work includes a pre-study of the programming language and the technology used. A concept for the solution is presented together with main components later broken down into internal functions. Following on this, other components that were necessary for fulfilling the function of the main components were identified. The system was developed with the hardware description language VHDL in order to be implementable and testable on an FPGA platform, but also to be transferable to other devices.

After the development and implementation on the hardware platform, the system was tested and verified. Analysis showed that some modifications were required to produce the desired results. These modifications implied some deviations from the assignment statement but gave rise to suggestions for further improvement of the concept. All in all, however, the solution was successfully verified since the transmitted data was possible to recreate the original image.

The report contains drawings of the developed system and the source code it consists of.
